As a wee bit of a drift are you still running the orginal linux cut down that your aspire one came with?
After a quick search I found a site that will show you where all the screws are to add memory so I stuck an extra 1G in.
I then put Fedora on it and boy does it rock now. No driver issues at all.
And its worth while finding out about the black screen of death on the aspire ones. The BIOS goes tits up and you have to reblow it. If you already have a USB stick with it on, you can sort it in 3 mins if you don't its a right pain in the bum.
